About Giant Gems

Giant Gems is one of the more simplistic video slots you are likely to come across in the online casino world. This particular title has been designed and developed by NextGen Gaming and can see players able to wager anything from 10p up to £200 a pop on its reels. There are 5 of those, upon which sit a total of 10 paylines. Those paylines are not adjustable. If you can’t tell from the title and the graphics which appear in this slot; Giant Gems is a gemstone themed video slot, and quite like the many others which appear in the online casino world. The game has a theoretical return to player (RTP) rate of between 93.75% and 96.13%, depending on where you play it, and a non-progressive jackpot which is capped at 500x your total bet.

Special features

One of the key things which are missing from this slot machine game is special symbols. There is no wild icon present in the game, nor are there any wild symbols for you to enjoy. Instead, players are going to have to rely on a few added perks. We’re going to call them bonus features, but in actuality, they are more like big bets and side bets than anything else.

Bonus features

The more a player chooses to wager, the better the features get. The standard game is played with 1-coin per spin bets. Place 2 or 4 coin spins, and you have the 10 removed and replaced with a purple gem, and the 10s and Jacks removed and replaced with purple and green gems. Playing with 6 coins with remove 10s, Jacks and Queens and replace them with purple, green and blue gems. Playing with a 10-coin spin can see all playing card symbols removed and replaced with gem symbols. Gem symbols are worth more than high playing card symbols, so the system is advantageous, if costly.


Personally, you shouldn’t be required to wager extra to have any special features. These big/side bets are fine, but they should not take the place of special features. One would expect to find free spins and/or wilds, and the lack of any is just bitterly disappointing.
